Yuck - I'll change the random state to be a bytevector to avoid these problems.

Fixed.  Note however that the random_r interface on Linux
doesn't seem to make saving and restoring state possible,
as initstate_r requires resetting with a seed, which is not
the same as setting the seed, generating some numbers,
and then setting just the random state.

You can reliably use random-source-pseudo-randomize!
with the same arguments for determinism.  Is there any
reason you need to use random-source-state-ref/set!
instead of this?

No good reason -- I was trying to get srfi-27's conftest.scm to run to 
completion for srfi-27 mashed into an r7rs library.
